Struct opentelemetry::sdk::metrics::aggregators::SumAggregator

pub struct SumAggregator { /* private fields */ }

Available on crate feature metrics only.

An aggregator for counter events.

Trait Implementations

impl Aggregation for SumAggregator

fn kind(&self) -> &AggregationKind

A short identifying string to identify the Aggregator that was used to produce the aggregation (e.g., AggregationKind::SUM).

impl Aggregator for SumAggregator

fn aggregation(&self) -> &dyn Aggregation

The interface to access the current state of this Aggregator.

fn update(
    &self,
    _cx: &Context,
    number: &Number,
    descriptor: &Descriptor
) -> Result<(), MetricsError>

Update receives a new measured value and incorporates it into the aggregation. Update calls may be called concurrently.

fn synchronized_move(
    &self,
    other: &Arc<dyn Aggregator + Sync + Send + 'static>,
    descriptor: &Descriptor
) -> Result<(), MetricsError>

This method is called during collection to finish one period of aggregation by atomically saving the currently-updating state into the argument Aggregator.

fn merge(
    &self,
    other: &(dyn Aggregator + Sync + Send),
    descriptor: &Descriptor
) -> Result<(), MetricsError>

This combines the checkpointed state from the argument Aggregator into this Aggregator. merge is not synchronized with respect to update or synchronized_move.

fn as_any(&self) -> &(dyn Any + 'static)

Returns the implementing aggregator as Any for downcasting.

impl Debug for SumAggregator

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for SumAggregator

fn default() -> SumAggregator

Returns the “default value” for a type.

impl Sum for SumAggregator

fn sum(&self) -> Result<Number, MetricsError>

The sum of the currently aggregated metrics
